Searching for and notifying a user to pick-up a printed document

ABSTRACT

Method(s) and apparatus(es) relate to notification to pick-up a printed document (“document”). In a method, stored are: at least one operation image of the document, and operation metadata and a user identity associated with a scanning or printing. A scan of at least one page of the document is received by the printer to generate at least one scanned image and scan metadata. The scan metadata is compared with data entries in a printer log to obtain a match to the operation metadata. The at least one operation image stored in relation to the operation metadata matching the scan metadata is retrieved. The at least one scanned image is compared to the at least one operation image. Responsive to determining the at least one scanned image matches the at least one operation image, sent from the printer is a confidential notification for the user identity to pick up the document.

TECHNICAL FIELD

The following description relates to a printed document. Moreparticularly, the following description relates to notifying a user topick-up a printed document.

BACKGROUND

Many offices may have a central printer for all or set of employees touse. For a printer, including without limitation a multifunctionprinter, a number of printed documents or other paper-based documentsmay be left at such printer. People may print documents and forget topick them up. Such printed documents may stay in a printer area for oneor more days and then may be thrown away or picked up by other employeesalong with their printed documents. This may lead to reprinting ofdocuments leading to wasting paper and energy, in addition to clutter ina printer area and potential disclosure of confidential information.

For security reasons, indicating who printed a document may not beposted with such printed document. Therefore, determining who printed adocument may be problematic.

SUMMARY

A method relates generally to notification to pick-up a printeddocument. In such a method, identity data is registered in memory of amultifunction printer for registered users thereof. For a printing orscanning operation of the multifunction printer associated with theprinted document, the following are stored in the memory of themultifunction printer: at least one operation image of the printeddocument; operation metadata associated with the scanning or printingoperation in a printer log; and a user identity associated with thescanning or printing operation. A selection of a search-notify functionof the multifunction printer is received. A scan of at least one page ofthe printed document is received by the multifunction printer togenerate at least one scanned image and query metadata. The querymetadata is compared with data entries in the printer log to obtain amatch to the operation metadata. The at least one operation image storedin relation to the operation metadata matching the query metadata isretrieved. The at least one scanned image is compared to the at leastone operation image. Responsive to determining the at least one scannedimage matches the at least one operation image to at least a thresholdpercentage, sent from the multifunction printer is a confidentialnotification for the user identity to pick up the printed document.

A multifunction printer relates generally to notification to pick-up aprinted document. In such a multifunction printer, memory of themultifunction printer is configured to register identity data ofregistered users thereof. The multifunction printer is configured tostore in the memory for a scan or print operation associated with theprinted document: at least one operation image of the printed document,operation metadata associated with the print or scan operation in aprinter log, and a user identity associated with the scan or printoperation. A search-notify function of the multifunction printer is toconfigure the multifunction printer to: execute a scan of at least onepage of the printed document to generate at least one scanned image andquery metadata; compare the query metadata with data entries in theprinter log to obtain a match to the operation metadata; retrieve the atleast one operation image stored for a match between the operationmetadata and the query metadata; compare the at least one scanned imageto the at least one operation image; and send a confidentialnotification for the user identity to pick up the printed documentresponsive to a determination the at least one scanned image matches theat least one operation image to at least a threshold percentage.

Other features will be recognized from consideration of the DetailedDescription and Claims, which follow.

For ease ofillustration, the same number labels are used in different diagrams torefer to the same items; however, in alternative examples the items maybe different.

Exemplary apparatus(es) and/or method(s) are described herein. It shouldbe understood that the word “exemplary” is used herein to mean “servingas an example, instance, or illustration.” Any example or featuredescribed herein as “exemplary” is not necessarily to be construed aspreferred or advantageous over other examples or features.

FIG. 1 is a flow diagram depicting an example of a frontend portion 100of a notification flow to pick-up a printed document. Frontend portion100 is for a preliminary portion of a notification flow, such asassociated with acts by a first user (“User A”).

At operation 101, users identity data (“identity data”) 115 isregistered or otherwise stored for purposes of retrieval. Such identitydata 115 may be registered in memory 120 of a multifunction peripheral(“MFP”), such as for example a multifunction printer, or in a cloudcomputing system or intranet. Such identity data 115 may be forregistered users of such an MFP. For purposes of clarity by way ofexample and not limitation, it shall be assumed identity data 115 isstored in memory 120 of an MFP.

For security reasons, any user may optionally have limited access tosuch identity data for purposes of making any changes thereto. Suchlimited access may be limited to administrative accessing 110.

At operation 102, a printing or scanning operation of an MFP may beperformed, such as by User A, on or for a printed document. At operation103, information associated with such printed document and operationtherefor may be stored, such as for example relationally stored inmemory 120 of such an MFP. Such information stored at operation 103 mayinclude at least one operation image 111, such as an image of a directprint or scan of such a printed document, and may include operationmetadata 112 associated with such operation conducted at operation 102as described below in additional detail.

For storing at least one operation image 111 of such a printed documentas part of operation 103, a set number of pages 121 may be set as amaximum number of pages of images for such an MFP to store for a printeddocument. In another example, for storing at least one operation imageof such a printed document, all pages 122, namely no maximum number ofpages of images, for such an MFP to store for a printed document may beset.

For storing at least one operation image 111 of such a printed document,an original resolution 123 may be set for such at least one operationimage for an MFP to store for a printed document. In another example,for storing at least one operation image 111 of such a printed document,a reduced resolution 124, such as for reducing memory requirementsand/or enhanced security, for such an MFP to store at least oneoperation image for a printed document may be set. In this example, atleast a 75% reduced resolution from an original printed sheet is used;however, in another example, a different reduction of resolution may beused. For this example, for an original resolution of 600 dpi (dots perinch) horizontally and vertically in each printed square inch of sheet,a 75% reduction in resolution may be 150 dpi horizontally and verticallyin each printed square inch scanned. Such a reduced resolution formatmay be preset.

Information stored at operation 103 may additionally include storedoperation metadata 112, such as scan metadata or print metadataassociated with a direct scanning or printing operation of such aprinted document using such an MFP. Relational storage at operation 103may use memory 120. In this example, a printer log 114, such as may bein memory 120, may be for operations conducted using an MFP. Along thoselines, operation metadata 112, which may be for a direct print or scanof a printed document using an MFP at operation 102, may be stored inprinter log 114. Furthermore, printer log 114 may include a pointer,generally indicated with arrow 116, to at least one operation image 111in relational association with corresponding operation metadata 112.

Information stored at operation 103 may include user identity data(“user identity”) 113 associated with a direct scanning or printingoperation document, using an MFP. User identity 113 may be of aregistered user in stored identity data 115 in memory 120. User identity113 may be considered part of operation metadata 112, but is separatedout in this example for purposes of clarity and not limitation.

User identity 113 may be stored in a secured manner. Furthermore, forsecurity reasons, user identity 113 may not be present on a printeddocument.

For purposes of clarity by way of non-limiting example, after a scanningor printing operation 102 using an MFP, a User A may not have retrievedsuch a printed document. For example, a User A may have forgotten totake with them or pick up such printed document. Other examples mayinclude: User A having thought such an MFP was a different MFP in anetwork with respect to printing a document; or location of an MFP maybe unknown to User A with respect to printing a document.

A subsequent user (“User B”) of such an MFP may find such printeddocument, and want to ping User A to retrieve such printed document, forany of a number of reasons. For example, User B may want to avoid havingclutter at such an MFP, unsecured printed documents at such an MFP,and/or having User A expend additional resources to reprint such aprinted document. Accordingly, a confidential notification to aregistered user associated with user identity 113 may be useful, asdescribed below in additional detail.

Registered users are not limited to employees of a company. Other typesof registered users, including guests, may be included. For example,when guests check into hotels, their information is stored in a hotel'ssystem. A guest may receive a key card to access property of hotel, andthis key card may be used to access a printer for example. For example,suppose a Guest ‘A’ can scan their key card, or enter their informationlike name, phone number, and/or room number, to use a hotel printer.Such a printer may record a time stamp when such printer was used byGuest ‘A’. A hotel system may have information of Guest ‘A’, such as forexample name, phone number, and/or email used for checking in. SupposeGuest ‘A’ prints a document ‘D’ and forgets to pick such document ‘D’up, and then Person ‘B’ arrives and finds document ‘D’. Person ‘B’ mayscan document ‘D’, and Guest ‘A’ may be identified for such document ‘D’as described herein. In this example, a time stamp of when a documentwas printed or scanned may be captured, and so such a system may seek tofind who logged into such a printer or an associated PC forcommunicating with such printer. After Guest ‘A’ is identified asassociated with such document ‘D’, a text message or email may be sentto Guest ‘A’ with a message along the lines of for example: “You forgotyour document by the printer, please pick up your document.”

FIG. 2-1 is a flow diagram depicting an example of a backend portion 200of a notification flow to pick-up a printed document. Backend portion200 is described further with simultaneous reference to FIGS. 1 and 2-1.

Backend portion 200 is for a post-preliminary portion of a notificationflow, such as associated with acts by a second user (“User B”) of suchan MFP. Accordingly, a combination of portions 100 and 200 may providean overall notification flow.

At operation 201, User B may select a search-notify function of such anMFP. After such a selection, User B may scan such a printed document onsuch an MFP. At operation 202, a scan of at least one page 250 of such aprinted document may be received by MFP to generate at least one scannedimage 252 and scan metadata 251. In another example, such scan of atleast one page 250 of such a printed document may be received or scannedby an MFP, and then at least one scanned image 252 and scan metadata 251may be uploaded at operation 202 to a cloud-based computing system.Accordingly, more than one page of a printed document may be included ina scanned image 252.

For storing at least one scanned image 252 of such a printed document, aset number of pages 221 may be set as a maximum number of pages ofimages for such an MFP or cloud-based computing system to store for aprinted document. Optionally, a User B may select a number of pages tobe scanned for a document, which may be as few as a single page. For acloud-based computing system, memory may be larger, and so a largermaximum number may be used. In another example, for storing at least onescanned image 252 of such a printed document, all pages 222, namely nomaximum number of pages of images, for such an MFP or cloud-basedcomputing system to store for a printed document may be set.

For storing at least one scanned image 252 of such a printed document,an original resolution 223 may be set for such at least one scannedimage 252 for such an MFP to scan for a printed document for storage insuch MFP or cloud-based computing system. In another example, forstoring at least one scanned image 252 of such a printed document, areduced resolution format (“reduced resolution”) 224, such as forreducing memory requirements and/or enhanced security, for such an MFPor cloud-based computing system to store at least one scanned image 252for a printed document may be set. Settings 121 through 124 maycorrespond to settings 221 through 224 for purposes of subsequentcomparison.

In this example, at least a 75% reduced resolution from an originalprinted sheet is used; however, in another example, a differentreduction of resolution may be used. Again, for this example, for anoriginal resolution of 600 dpi (dots per inch) horizontally andvertically in every printed square inch of sheet, a 75% reduction inresolution may be 150 dpi horizontally and vertically in every printedsquare inch scanned. Such a reduced resolution 224 may be preset for ascanning operation responsive to selection of a search-notify functionat operation 201.

At operation 203, search-notify scan (“query”) metadata is compared withstored data, or more particularly stored operation metadata 112, entriesin a printer log 114 to obtain corresponding, or more particularlymatching, stored operation metadata 112. This comparison may beperformed by a notify application of an MFP or by a backend applicationof a cloud-based computing system, as described below in additionaldetail.

In this example, at operation 204, it is determined whether there is amatch between query metadata 251 and operation metadata 112 stored inprinter log 114. If no match is found as determined at operation 204, atoperation 209 a no match found message may be displayed, such as forexample on a display of such an MFP. In this example, an exact matchthreshold is used. However, in another example a less than an exactmatch threshold may be used for comparing query metadata 251 andoperation metadata 112.

For a match between query metadata 251 and operation metadata 112 atoperation 205, user identity 113 corresponding to such matchingoperation metadata 112 may be obtained from printer log 114. However,such corresponding user identity 113 may not be directly obtained atthis juncture for purposes of additional security and/or confirmation byuse of an additional optional check using images.

For a match between query metadata 251 and operation metadata 112 atoperation 205, such an at least one operation image 111 stored inrelation to such operation metadata 112 matching query metadata 251 maybe retrieved.

At operation 206, such at least one scanned image 252 associated withmatching query metadata 251 may be compared to such at least oneoperation image 111 retrieved in relating to matching operation metadata112. For this example, a comparison operation 206 may be performed by anotify application of an MFP or by a backend application of acloud-based computing system.

In this example, a match at operation 204 may not be sufficient forconfirming and/or securing identity of an owner of a document, and so asecond optional check for a match, though not necessarily an exactmatch, at operation 207, using optional operations 205 and 206, may beused to bolster confidence in owner identity.

Responsive to determining at operation 207 such at least one scannedimage 252 matches at least one operation image 111 retrieved atoperation 205 to at least a threshold percentage, at operation 208 suchan MFP or cloud-based computing system may send a confidentialnotification to a user identity 113 associated with matching operationmetadata 112 to pick up such a printed document. If no match is found asdetermined at operation 207 to at least a threshold percentage, atoperation 209 a no match found message may be displayed on a display ofsuch an MFP. A threshold percentage in this example is 80%; however, inanother example, a lower or higher threshold percentage may be used.

Such a confidential notification sent at 208 may be by email 211 and/ortext message 212. This confidential notification may be sent from suchan MFP or cloud-based system without revealing User A identity to UserB. Again, user identity 113 may be found with a match at operation 204,and this user identity 113, such as for a User A, need not be displayed,such as for example on a display of an MFP. Optionally, at operation208, such an MFP or cloud-based computing system in response to sendinga confidential notification may display on a display screen thereof atoperation 233 to indicate a message was sent to an owner of such printeddocument without revealing user identity 113 of such owner.

Optionally, at a location of an MFP, there may be a safe with anelectronic pad (“electronic safe”) for opening, closing, locking, andunlocking. Accordingly, at operation 210, User B may put such a printeddocument in such an electronic safe and lock it via such pad. Such anMFP or cloud-based computing system may be in communication with such anelectronic safe for setting a code for unlocking such electronic safe. Aconfidential notification sent at 208 may include a code for openingsuch electronic safe.

FIG. 2-2 is a flow diagram depicting an example of operations 206 and207 of FIG. 2-1 for an example of a backend portion 200. This example ofbackend portion 200 is described further with simultaneous reference toFIGS. 1 through 2-2.

At operation 213, a comparison of at least one scanned image to at leastone operation image may be performed on a pixel-by-pixel basis. In thisexample, such first pixel-by-pixel basis may be with pattern matching atoperation 214.

At 215, if a match was found by a comparison at operation 213 to atleast a threshold percentage, then, for this example, notification flow200 may resume at operation 208. If, however, no match was found by acomparison at operation 213, as determined at operation 215 to at leasta threshold percentage, then, for this example, notification flow 200may at operation 216 optionally perform another comparison of at leastone scanned image 252 to at least one operation image 111 on a differentpixel-by-pixel basis. In this example, such second pixel-by-pixel basismay be with image edge detection matching at operation 218.

At 217, if a match was found by a comparison at operation 216 to atleast a threshold percentage as determined at 217, then in this examplenotification flow 200 may resume at operation 208. If, however, no matchwas found by a comparison at operation 216 to a threshold percentage asdetermined at operation 217, then in this example notification flow 200may resume at operation 209.

FIG. 2-3 is a flow diagram depicting an example of purge operations 220for another example of a backend portion 200 of FIG. 2-1. This exampleof backend portion 200 is described further with simultaneous referenceto FIGS. 1 through 2-3.

From operation 208, a determination may be made whether to purge memory120, such as one or more data entries in printer log 114. A purgingoperation may be based on an amount of memory 120 used for a printer log114 and/or a period time or other time parameter for a periodic purging.These settings may be set at operation 221 with administrativeprivileges. If a purging operation is to be performed as determined atoperation 219, then at operation 222 at least one operation image 111and associated operation metadata 112, including user identity 113, maybe purged or deleted from printer log 114 in memory 120. After purgingat operation 222, a notification flow may resume or wait for anotherselection at operation 201. However, if no purge is to be performed asdetermined at operation 219, a notification flow may resume at operation201.

FIG. 2-4 is a flow diagram depicting an example of another backendportion 200A of a notification flow to pick-up a printed document.Backend portion 200A is described further with simultaneous reference toFIGS. 1 through 2-4.

Backend portion 200A is for post processing with respect to frontendportion 100, such as associated with acts by a second user (“User B”) ofsuch an MFP. Accordingly, portions 100 and 200A may be combined asdescribed herein to notify a user.

In this example, such a printer or MFP does not have a scanner, or aworking scanner. Along those lines, at operation 201A, a snap-notifyfunction may be executed on a snap-notify application of a mobile devicein communication with such an MFP or a cloud-based computing system. Inanother example, at operation 201A, a snap-notify function may beexecuted on a snap-notify application of such an MFP in communicationwith such a mobile device with a camera or a wireless camera and incommunication with a cloud-based computing system. A network, wired orwireless, may be used for communication with such a mobile device asbetween such a printer and/or cloud-based computing system. Execution ofsuch a snap-notify function may cause a camera of such a mobile deviceto be activated. A wireless network may be used for communication withsuch a wireless camera as between such a printer and/or cloud-basedcomputing system.

Using such snap-notify application, User B may photograph one or morepages of a printed document using such camera to obtain at least onephotograph 250P. At operation 202A, a photograph of at least one printedpage of such printed document is received via such camera, and at leastone photo image 252P and associated photo metadata 251P therefor of suchat least one photograph 250P is uploaded and stored, such as in acloud-based computing system or in an MFP.

Optionally, such a snap-notify application may be configured to notstore, or only temporarily store, photos 250P taken with such cameraunder execution of such a snap-notify application. Along those lines,after uploading from a mobile device or wireless camera to a cloud-basedcomputing system, such mobile device or wireless camera may beconfigured via such snap-notify application to delete such uploadedphoto image(s) 252P and associated photo metadata 251P from its ownmemory. However, in this example, a photograph 250P of at least oneprinted page of a printed document via a camera may be stored as atleast one photo image 252P along with associated photo metadata 251P ina mobile device.

For storing at least one photo image 252P of such a printed document, aset number of pages 221 may be set as a maximum number of pages orimages for such at least one photo image 252P to store for a printeddocument. In another example, for storing at least one photo image 252Pof such a printed document, all pages 222, namely no maximum number ofpages or images, to store for a printed document may be set. Again, aUser B may determine how many photos to take.

Furthermore, a User B need not scan or photograph starting from page 1and progressing sequentially through a document. For example, a User Bmay start at any page and randomly select one or more other pages tophotograph or scan. Page numbers on a printed document may be used todetermine which pages to use for purposes of comparison; or a User B mayinput which pages were scanned or photographed.

For storing at least one photo image 252P of such a printed document, anoriginal resolution 223 may be set for such at least one photo image252P for such an MFP or in a cloud-based computing system to store for aprinted document. In another example, for storing at least one photoimage 252P of such a printed document, a reduced resolution 224, such asfor reducing memory requirements and/or enhanced security, for such anMFP or a cloud-based computing system to store at least one photo image252P for a printed document may be set. Settings 121 through 124 maycorrespond to settings 221 through 224 for purposes of subsequentcomparison.

In this example, at least a 75% reduced resolution from an originalprinted sheet is used; however, in another example, a differentreduction of resolution may be used. Again, for this example, for anoriginal resolution of 600 dpi (dots per inch) horizontally andvertically in every square printed inch of sheet, a 75% reduction inresolution may be 150 dpi horizontally and vertically in every squareprinted inch scanned. Such a reduced resolution format may be preset fora photographing operation to obtain at least one photograph 250Presponsive to execution of a snap-notify function at operation 201A, orsuch a reduced resolution format may be obtained by a conversion of atleast one photograph 250P after a photographing operation 201A toprovide at least one photo image 252P.

At operation 203A, photo metadata 251P is compared with data entries ina printer log 114 to obtain a match to stored operation metadata 112. Atoperation 204A, it is determined whether there is a match as betweenphoto metadata 251P and operation metadata 112, such as stored inprinter log 114 for example. If no match is found as determined atoperation 204A, at operation 209 a no match found message may bedisplayed on a display of such an MFP. In this example, an exact matchthreshold is used. However, in another example a less than an exactmatch threshold may be used.

Along those lines, a photo image of a printed document may be comparedwith print metadata 251P stored on a printer for example. For purposesof clarity by way of non-limiting example, print metadata 251P mayinclude information such as color or BW, page size (e.g., A4, letter,legal, etc.) and/or number of pages. To obtain information about pagesize from photo data, an image-to-image comparison may be performedusing keypoint extracting, keypoint matching, scale-invariant featuretransforming (e.g., SIFT) of keypoints, and/or other image-to-imagefeature extraction technology for purposes of image-to-image comparison.

For a match between photo metadata 251P and operation metadata 112, atoperation 205A, such an at least one operation image 111 stored inrelation to such operation metadata 112 matching such photo metadata251P may be retrieved. At operation 206A, such at least one photo image252P for such matching photo metadata 251P may be compared to such atleast one operation image 111 retrieved.

If a match is determined to a threshold percentage at operation 207A,namely one or more photos match corresponding operation images to atleast a threshold percentage, at operation 208 such an MFP orcloud-based computing system may send a confidential notification to anidentified user to pick up such printed document. If no match is foundto at least a threshold percentage at operation 207A, at operation 209 ano match found message may be displayed on a display of such an MFP ormobile device. A threshold percentage in this example is 80%; however,in another example, a lower or higher threshold percentage may be used.

A confidential notification sent at 208 may be by email 211 and/or textmessage 212. This confidential notification may be sent from an MFP orcloud-based computing system without revealing User A identity to UserB. Again, user identity 113 may be found with a match at operation 204A,and this user identity, such as for a User A, need not be displayed on adisplay of an MFP or mobile device for sending a confidentialnotification. Optionally, at operation 208, an MFP or cloud-basedcomputing system in response to sending a confidential notification maydisplay on a display screen of such MFP or mobile device at operation213 to indicate a message was sent to an owner of a printed documentwithout revealing user identity 113 of such owner.

Optionally, at a location of an MFP, there may be a safe with anelectronic pad (“electronic safe”) for opening, closing, locking, andunlocking. An electronic safe may be in communication with an MFP orcloud-based computing system for setting a code for unlocking. Aconfidential notification sent at 208 may include a code for openingsuch an electronic safe. Accordingly, at operation 210, User B may put aprinted document in an electronic safe and lock it via a pad.

FIG. 3 is a block diagram depicting an example of a registered usersrecord or table (“table”) 300. Such registered users record includesidentity data, such as identity data 115 and may be for registered usersof an MFP, as previously describe with reference to FIG. 1.

There may be rows of user identity records in table 300 for eachregistered user. For example, a user identity 310 in a row of table 300may include a user device address field 301, an email address field 302,and optionally a user name field 303. Accordingly, there may be a userdevice address, an email address, and optionally a user name for eachregistered user for an MFP. A confidential notification for example maybe an email sent to a registered user of such registered users for auser identity found from a match, as previously described.

FIG. 4 is a block diagram depicting an example of a printer log 400.FIG. 5 is a block diagram depicting an example of an operation metadatarecord 500. FIGS. 4 and 5 are further described with simultaneousreference to FIGS. 1 through 5.

A printer log 114, such as may be in memory 120, may be for operationsconducted using an MFP as previously described with reference to FIG. 1,and printer log 400 may be an example of a printer log 114.

Printer log 400 may be a table for relationally storing information;however, another type of relational data storage may be used. Each dataentry row 410 may include at least one operation image 411 as previouslydescribed for a printed document. Each data entry row 410 may furtherinclude operation metadata 412 and user identity 413 each associatedwith such at least one operation image 411, such as previouslydescribed. Each data entry row 410 may include user identity or apointer to user identity 413.

The term “transmission media”, which includes coaxial cables, conductivewire and fiber optics, including traces or wires of a bus, may be usedin communication of signals, including a carrier wave or any othertransmission medium from which a computer can read. Transmission mediacan also take the form of acoustic or light waves, such as thosegenerated during radio-wave and infra-red data communications.

Various forms of tangible signal-bearing machine-readable media may beinvolved in carrying one or more sequences of one or more instructionsto CPU 704 for execution. For example, instructions may initially becarried on a magnetic disk or other storage media of a remote computer.The remote computer can load the instructions into its dynamic memoryand send such instructions over a transmission media using a modem. Amodem local to computer system/MFP 700 can receive such instructions onsuch transmission media and use an infra-red transmitter to convert suchinstructions to an infra-red signal. An infra-red detector can receivesuch instructions carried in such infra-red signal and appropriatecircuitry can place such instructions on a bus of computing device 710for writing into main memory, from which CPU 704 can retrieve andexecute such instructions. Instructions received by main memory mayoptionally be stored on a storage device either before or afterexecution by CPU 704.

In any such implementation,a communication interface sends and receives electrical, electromagneticor optical signals that carry digital and/or analog data andinstructions in streams representing various types of information.

A network link to local network 722 may provide data communicationthrough one or more networks to other data devices. For example, anetwork link may provide a connection through local network 722 to ahost computer 724 or to data equipment operated by an Internet ServiceProvider (“ISP”) 726. ISP 726 may in turn provide data communicationservices through a world-wide packet data communication network, the“Internet” 728. Local network 722 and the Internet 728 may both useelectrical, electromagnetic or optical signals that carry analog and/ordigital data streams. Data carrying signals through various networks,which carry data to and from computer system/MFP 700, are example formsof carrier waves for transporting information.

A computing device can include wirelesscircuitry that can communicate over several different types of wirelessnetworks depending on the range required for the communication. Forexample, a short-range wireless transceiver (e.g., Bluetooth), amedium-range wireless transceiver (e.g., WiFi), and/or a long rangewireless transceiver (e.g., GSM/GPRS, UMTS, CDMA2000, EV-DO, andLTE/LTE-Advanced) can be used depending on the type of communication orthe range of the communication.

Computer system/MFP 700 can send messages and receive data, includingprogram code, through network(s) via a network link and communicationinterface of I/O interface 702. In the Internet example, a server 730might transmit a requested code for an application program throughInternet 728, ISP 726, local network 722 and I/O interface 702. Receivedcode may be executed by processor 704 as it is received, and/or storedin a storage device, or other non-volatile storage, of memory 705 forlater execution. In this manner, computer system/MFP 700 may obtainapplication code in the form of a carrier wave.
